We had been sitting in our hot tub outside on our deck ,myself for 25 minutes, when We sighted a blueish white sphere in the, clear of clouds, southern sky at @730p very low on the horizon approximately the size of a tennis ball that suspended in one spot and then shot westward extremely fast leaving a bluish white trail. The sighting lasted 3-5 seconds. Just long enough for me to query "Did you see that?"...It apeared much like a falling star with an exagerated descent except for the closeness and the size of the object. We both had never seen anything like it and were looking for other places such as news programs to see if others had seen this as well.we both have had many years in aviation and sky watching. This was a novel sighting for both of us. There were aircraft in the sky at this time as well in that we live close to MHT airport. We were hoping that maybe a pilot might have witnessed this.
